SEWING Device.

SPECIFICATION forming part of Letters Patent No. 744,080, dated November 17, 1903.

Application filed June 6, 1903. Serial No. 16G333. (No modelii To all whom it may concern:

Be it known that I, OSCAR KNORR, a citizen of the United States,residing at Ohicago,Oook county, Illinois, have invented certain new and useful Improvements in Sewing Devices, of which the following is a specification.

This invention relates to sewing devices, and has particular reference to needle-guides in patchwork.

. coacting member; and the invention further consists in the novel details of construction and combinations of parts hereinafter del scribed in detail, illustrated in thedrawin gs, and pointed-out in the claim.

The invention will be more readily understood by reference to the accompanying drawings, forming a part of this specification, and in Which- Figur-esl and 2 represent the opposite sides of a pair of clamping members together forming a guide embodying my invention, and Fig. 3 represents the guide with its members in operative position and a needle therein.

In the drawings, 2 represents a corrugated metallic plate having grooves and ribs intertitting with the grooves and ribs of another similar plate. Each of these plates is pro- 1 vided with a series of apertures 4, forming Vthrough the rows of holes, forming a series of regular stitches. When the stitches have been completed in one direction, the plates 2 f and 3 may then be placed so that the rows of holes will run at right angles to the stitches already formed. The latter will then be al- `terna'tely depressed and raised, so that when transverse stitches are made the needle will pass alternately above and below the threads in the manner of a shuttle inra loom, thus interweavin g the threads. If desired, the operation maybe repeated by placing the platesl diagonally across the patch formed. When the work is finished, it will be found that the parallel threads will be rregular distances apart,and as the portion patched is held firmly between the plates there will be no danger of drawing somethreads too tight across the space patched and others too loose.

While for the purpose of clearly illustrat ing the idea in my invention I have shown the corrugations as quite deep, the latter are preferably made shallower in practice to avoid undue shrinking of the part patched, as all that isnecessaryv is to corrugate the surface just sufficient to permit the needle to pass between alternate threads or series of threads in the' cloth or patch.

The members 2 and 3 of the guide or clamp may be made from solid blocks of wood or metal grooved and slotted on one side to form a surface corresponding to that shown in Fig. 2, in which event the opposite surface, or that represented in Fig. l, would be smooth. It is understood that the spirit of my invention does not contemplate a pair of corrugated sheets of metal vso much as the two coacting adjacent surfaces grooved and slotted in the manner represented by the upper part of Fig. 2 and lower part of Fig. l. The solid-block form of my device would not so clearly illustrate the twomembers in juxtaposition as the corrugated plates in Fig. 3. The serrated edges of the plates (represented by numeral 6) and which together form the ICO apertures 7 in Fig. 3 will in practice be made sufficiently thick to provide needle-bores of sufiicient length to guide the needle straight to the second hole from the edge across the plate of each transverse row of holes.

For coarse interweaving of threads the plates 2 and 8 may be corrugated transversely as Well as longitudinally and provided with suitable intersecting slots, and it is obvious that my invention is susceptible of numerous other modifications in its embodiment Without departing from the spirit thereof, and I therefore do not conne same to the specific construction herein shown and described.

Having thus described my invention,r I

OSCAR KNORR.
